The two types of feldspar are usually near from, respectively: (1) plagioclase i.e. member of the Anorthite-Albite series (=CaAl2Si2O8-NaAlSi3O8) (2) alkaline feldspar i.e. member of the Orthoclase-Albite series (=KAlSi3O8-NaAlSi3O8).
Low-cost heat treatment process for superalloy disks: higher rim-temperature capabilities would increase gas turbine engine efficiency. A new solution heat-treatment technology that produces a fine grain bore and coarse grain rim is a step in that direction.(Heat Treating)
